nE'raoHABLn WHEEL.

To all whom it may concern Be it known that I, RIoHAnn S. BRYANT, a citizen of the United -States, and a resident of Cleveland, county of Cuyahoga, and State 5 of Ohio, have invented a new and useful Improvement in Detachable NVheels, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have .10 contemplated applying that principle, so as.

to dist nguish it from other inventions.

The present improvements, relating as indicatedto detachable or demountable wheels, have as their object thelprovision of a .construction of double hub consisting of an inner sleeve normally rotatably secured to the vehicle axle and an outersleeve or shell to which the inner ends of thespokesare fixed, which outer shell is normally fixedly secured on the inner sleeve, but maybe removed therefrom when desired.

A further object of the invention is to provide a construction of the foregoing description, which willbe simple and compact and yet insuresafety'against accidental separation of the two "hub parts at all times.

To the accomplishment of these and'related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed: out in the claims.

The annexed drawings and the-following description set forth in detailcertain mechanism embodying the invention,' such disclosed means constituting, however, but one of various mechamcalforms In which the same modification.

the hub members.

tion 8 is substantially cylindrical, being externally threaded to receive an internally threaded cap or nut 9 whichcloses the end of said inner hub member and also serves to secure the outer hub member 10 firmly thereon, as will be presently described. The tapering, or beveled, portion of said inner hub member is provided with a series of longitudinallyextending ribs 11 as clearly shown in Figs. 1 and 2, the forward ends of said ribs being rounded or beveled slightly so as to facilitate their locking engagement with grooves 12, which are formed on the inner face of the outer removable hub member.

The latter supports the wheel structure beveled surface against which the inner edge of the retaining cap 9 may be pressed, the

latter being correspondingly beveled so as to have a wedging engagement with the former. In assembling the wheel, accordingly, the outer hub member, being placed on the inner hub member with its grooves 12 en gaging with the ribs 11 on the latter, is forced into tight engagement with such ribs by drawing up the securing-cap so that the two hub members constitute, in effect, an

The cap 9 is furthermore desirably rotatably secured to said outer hub member, so as to be removed therewith. To this end, I may employ the construction shownin Fig. 1, whereby said cap is rotatably locked to the hub member through the medium of a plurality of balls 15 held in a race formed by a channel 16 encircling the cap and a. groove 17 formed in the outer hub member by slightly recurving its extreme outer edge. As a result of thus securing the cap to the hub member, said cap not only serves to firmly seat the hub member as above described, but upon rotating the cap in the opposite direction, it relieves the seating pressure on the hub member and also positively withdraws the latter from engagement with the inner hub member, so that as soon as the threads of the cap are entirely imscrcwed,

the wheel is sufficientlyloosened to permit its ready removal.

To facilitate the lubrication of the bearings within the inner hub it is desirable to have'a hole for lubricant eXteLding through Accordingly, as means forconveniently securing an opening, whereby access may thus be had. for lubricant to the interior of the hub structure, I. provide a. series of apertures 18 in a circle surrounding the inner hub member, one

' aperture being located between each tongue or rib 11. The outer hub member, thenfis provided with a single aperture 19 located midway between any two of the complemen tary grogves 12 in its inner surface, so that no matter where the outer hub member may be seated on the inner hub member, a direct opening into the interior is assured. A closure, or cap 20, of any suitable design, such as shown in Figs. 1 and 2, may be used in connection with the opening in said outer hub member.

Aside from showing hub members adapted 'to be mounted on a front wheel spindle, Figs. 3 and it show a modification in the construction of retaining cap 9. In the first place, the beveled edge of such cap, designed to engage with the flaring portion ll of hill) member 10 is provided with a series of short slots 22 after the fashion of a collet, thus insuring better wedging action. In the second place, instead of balls 13, a series of pins 23, are utilized to rotatablysecure the cap to the hub member. These pins project through suitable apertures in the cap, being provided with beads 2i adapted-to seat in a groove 25 formed on the inside of such cap. A transversely split annular spring 26 is adapted to hold these pins in place by pressing outwardly against their heads, and when thus in place their ends project sufficiently to engage the inwardly curved edge of the hub member, just as do the balls in the first-described construction.

Either form of construction, it will be evident, provides an extremely simple and compact hub despite its double character. The means of locking the outer member against rotation on the inner member may be made amply strong to withstand any strain, while the cap 5) serves both to lock said outer hub member against longitudinal movement on the inner hub member, and to remove the former from the latter when desired. The only ii'nplement required in mounting, or demounting, the wheel, is a wrench, the cap being provided on its outer face with a nut 27 for use with such wrench. The cap is also provided on its inner face with a threaded hole 28 to receive a bolt, whereby a closure plate (not shown) may be secured on the rear end of the outer hub member when the wheel isdclached.

()ther modes of applying the principle of my invention may be employed instead of the one explained. change beingmade as regards the mechanism herein disclosed, provided the means stated by any of the-following claims or the equivalent of such stated means be employed.
